They are Layer-3 switches, if I understand correctly. They do work at
level 3 of the OSI as the routers but, again, if I understand correctly,
routers now are more on the edge of the network and the layer-3 switches
are at the core ( the LAN part ). The routers will handle serial
connection besides ethernet connections, and layer-3 switch won't handle
serial connections. Also the routers will use more software for
routing, and layer-3 switch use more hardware for routing.
